Hi I have a 2011 SMS630 which starts for a few seconds then cuts out
Symptoms are
Ignition on fuel pump primes
Hit starter engine starts then cuts out no spark pump dosnt reprime and flashing neutral light 4 bins stop 4 blinks stop
Switch ignition off and on again pump primes spark returns engine fires up sounds good then cuts out same again
I know the flashing neutral light is telling me there's a fault code but can't find anything that will read it
So 2 questions has anyone else had this problem (k own fault) or dos anyone have a I beat system for sale or who could read my ecu as I'm stuck
Any help greatly appreciated
Thanks phil
 
You could try checking the individual fuel injection related components to see which one is causing the errors. Resistance values are located in section M of service manual. Do you have access to a manual?
